1993 CBR900RR - rebuilding an iconic super sport
« on: Oct 16, 2012, 22:00:36 »
Hi folks,

Either because of or in spite of the advice that I received on this forum, I picked up a '93 CBR900RR at auction.  Looks like she ran into something hard at speed, mushed the forks into the exhaust, and cracked up some of the fairings. 





Reminds me of this  :o



Plan is to get the bike back together to stock and move it on to a new home.  Sometimes we build them to fund real life, right?  :)

Considering the time and money involved with "restoring" this scoot, I say turn it into a straight up street fighter. Basically, replace only what needs replacing to get her on the road. Just my two cents.

I stripped the ruined forks and fairings off of the CBR to get an idea of what I was dealing with.  I knew worst case I could come out ahead parting it out, but was hoping that it was rebuildable, as that's more fun (and more profitable! ;D )



Good bones!



Hrm, need a replacement fairing stay bracket



Not sure this will buff out  :P

I pulled the tank (slightly old smelling gas, but no more than a month I'd judge), and checked the air filter.  The air filter looked brand new - that's a good sign!  I opened up the throttle and told the carbs to say "ahhh!" and they were clean as a whistle.  Also good!

The oil filter was mushed along with the header pipes, but was not leaking oil.  I replaced it, checked coolant and oil levels (full of coolant and clean oil, yay!), and was able to get the bike fired up in short order using nothing more than the choke.  The bike sounds strong and mean with the bolt on aftermarket exhaust.  It settled right into a nice idle, and I was content at that and shut her down.

So, parts list; the bike needs:

header pipe
forks
front axle
one brake rotor
fairing stay brace
brake side rearset bracket

to be rideable.  At that point the bike could be sold and ridden away, so that's my first milestone.

Moving on from there, a lot of the plastics can be repaired - they only have one crack or one or two broken tabs, and some of the plastics have no damage at all.  The headlight fairing and headlights will need to be replaced, however.

Forks, brake rotor, front axle, headers, and instrument / fairing bracket on their way, along with an original dealer issue service manual.  Yay Ebay!

Time to find a right side rearset mount, and it will be an actual bike (some assembly required).  I also have to check out the bearings to make sure they weren't cooked in the accident.  Good news is that they are inexpensive!

Yea, getting it going down the road is step one; the parts on the way are what is needed to get it rolling.  I know the fairings look rough, but the "nose" is the worst of it.  I have to go through the fairings and see what can be repaired and what needs to be replaced.  You guys will be the first to know!  ;D

Maybe it's the angle of the picture, but it looks like the frame is bent....Is the steering neck stressed looking? The neck takes a lot of force in an accident like that..

It's the angle of the picture - the steering neck is fine and the neck bearings are even still tight  :o  I'll probably replace them anyway. 

I spent part of today gluing the cracks in the faring pieces together with Devcon Plastic Weld epoxy.  We'll see how it turns out, but epoxy is cheap and fairings are expensive  ;D

Now it's hurry up and wait for more Ebay parts to arrive - the instrument cluster / fairing stay bracket arrived today, as well as a pristine factory service manual.  Anyone have a spare headlight assembly and fairing nose lying around?  :D

Great project.  I was just at a moto flea market a few weeks back that had that exact front fairing you need.  Talked myself out of buying it... damn.

Son of a...if you come across it again, let me know.  They are not cheap, and I don't know how well epoxy will hold what's left of this one together.  Thanks!
